DEVICE FOR OILING AXLE-SPINDLES 'WITH HARD OIL.

Specification of Letters Patent.

Application led June 25, 1917. SerialNo. 176,890.

To all/whom it may concern:

Be it known that I, EDMUND H. Cassin., a citizen of the United States, and resident of Madrid, in the county of Boone and State of Iowa, have invented a. certain new and useful Device for Oiling AXle-Spindles with Hard Oil, of which the following is a Specification.

The object of my invention is to provide a simple, durable and inexpensive Vdevice for oilin axle spindles with hard oil for maintaining a continuous and uniform distribution of the oil over part of the spindle which endures the greatest friction.

` Still a further object is to provide such a device which will thoroughly oil the spindle at the end carrying the nut.

.With these and other objectsvin view, my invention consists in the construction, arrangement and'combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of a hub and part of the spokes of a vehicle wheel, equipped with an oiling device embodying my invention.

Fig. 2 shows a transverse, vertical, sectional view of the same, and

Fig. 3 shows a top or plan view` of the spindle with the sleeve which forms the inner part of the hub mounted thereon, illustrating the peculiar shape of the slot in the sleeve.

'In the form of my invention illustrated in the accompanying drawings, I have used the reference numeral 10 to indicate generally the axle of a vehicle having at one end the tapered spindle 11. The spindle 1 1 is provided at its free end with a reduced cylindrical, externally screw-threaded extension l2 to receive lthe nut 13 which holds the wheel on the spindle.

j 1 have shown a portion of a wheel having e. hub formed with a central sleeve 14 which ts snugly on the spindle 11 and is tapered to correspond to the shape of the spindle.

Surrounding the sleeve 14 is a hub casing member 15 having the anges 16 for the inner ends of the'spokes 17.

rllhe hub casing 15 is provided with a compertinent or enlarged portion 18 designed to receive an oil tube 19. The compartment 18 and the portion of the oil tube 19 received therein are preferably tapered soxnewhat from end to ond.

The oil tube' 19 projects laterally and thence radially outwardly from the larger end of the compartment 18 and has onits. outer end a grease cup 20. shown in Fig. 2.

The sleeve 14 is provided with a longitudinal slot 21 having at its endsportions Q2 ofisetcircumfcrentially of the sleeve 11 from the body of said slot.

The purpose of the peculiar configuration of the slot 22 is to avoid' along, longitudinally arranged slot which would weaken the sleeve as a bearing for receiving the spindle' 11, and 'to avoid leaving a considerablearea in one longitudinal section of the sleeve which has no solid metal bearing against the spindle 11. The grease tube 19 is provided with a plurality of openings Q3. Q4, and 27 which register with the slot 21 and the portions 22 thereof, which openings gradually increase in size from the opening 2.2 to the opening 27 so that the large openings are the ones farthest removed from the grease cup. No openings are provided near the longitudinal centerof the axle since grease tends to rollect there in any event.

y Near the inner and Outer ends of the spindle the sleeve 14 is provided with oponings 2.8 which register with similar openings 29 in the tube 19.

At the outer end of the tube 19 is an open-y ing 30 through which oilv may pass to the nut 13.

It will thus be seen that the arrangement of my improved oiling device is such as to supply oilv to the ends of the spindle. In this connection it should be mentioned that the ends of the spindle are the parts which become dry first.

Formed on the casing 15 is a cylindrical,

lateral extension 31, externally screw-thread I ed to receive the cap 32..

The device may be made with or without the cap 32, but when the .cap 32 is used, it will be obvious that an oil space is piovided which will make it possible for the outer end 4of the spindle and the nut 13 to tra l in oil..

The advantages of a device of t e kind herein described, may be largely seen from the foregoing description.

j 1t will he obvious that the arran einent of the oil .passages and openings is sac.. to

Life2' Sw eil-Ford ample supply of oil to of' the spindle 3, as long as there is oil in the 'tube 29, i

It is e simple problem to supply new oil to a device et this kind, for the ieason that the cup 2G inegi oe removed and oil loe forced into the tulle 19 and the cup :2O may be idlled, and the eup i2() ie screwed on the tube tiie loaifd oil will. loe foreed in the eeoesses'ot the tube il?.

The peouiia ai'rainfjfeinent of the slot is suoli as to avoid a long, straight slot in the ele-eve 15e, u'liieii might weaken suoli sleeve and impair its eilioienojy as a bearing, and yet on aeoount of the fact that the slot 2l is of considerable length, it is obvious that it may be entirely lilled with oil throuijli the 'Various openings to 2'? inclusive, so that it Wiil aiord an ample supply oi'l oil to the entire central portion of ine spindle 1l.

The outer end of tile spinde and the nut thereon may be fun in oil Wlere the extension 3l and oep 32 are enipleved.

Some changes may be infile in die oonstruotion, arrangement and -onibinoiion of the various ports of my improved def-fine, Without `depaiting from the read spirit and purposes oli my invention, a xd it is my in tention to cover the patent to be issued on. my application, any euehinodiiied forms ot' structure or use of ineeliai'iioal equivalents, wliieli may 7oe reasonably included Within the scope of my Claims.
